Hi, i m serious freelancer with 100% completion rate and i believe i can help you. This is really simple to do, just pm me and i will send you a demo (that i already created) that works exactly as you want it. It took me 10 minutes to write excel macro for this, thats why i need to tell you that your budget is way bigger then it should be. I would do this for 10$. So if you are interested just message me and i will send you a demo to see.
Thanks, Milan
